ME020418 - TRB: Message contains bare line feeds (LF's) and is being rejected


SYMPTOMS

Some mail servers refuse to accept mail, and advise that the message contains "Bare LFs"

"Bare LFs" is explained in detail at the following location:

http://cr.yp.to/docs/smtplf.html

CAUSE

MailEnable does not generate any messages that contain bare line feeds. All MailEnable generated messages contain both the carriage return and line feed.  MailEnable is not the cause of this problem.

Possible causes follow:

A) MailEnable is receiving the messages with bare line feeds and is then passing them on to the downstream server

B) A third party program is generating these messages.

SOLUTION

For Cause A)...

By reviewing the logs, it should be possible to determine who/what is generating the messages.

For Cause B)...

Review any pickup events or the use of third party mailer applications that could cause this issue.
